Aún sigo teniendo sueño, voy a dormir un poco mas.
No. If you ran faster that would mean you weren't at the house yet.
The sentence is incorrect because of the words dorms and Queen .
The correct sentence is Es importante que duermas un poco antes de la excursión.
Hope this helps and have a wonderful day!
What's the question? I am Mexican American and I don't understand what you're trying to ask.
